DRV612RGTT

Audio Amplifiers Overview

The DRV612RGTT is a single-ended stereo line driver utilizing DirectPath technology, eliminating the need for output DC-blocking capacitors. It operates on a single 3-V to 3.6-V supply and delivers 2 Vrms into a 600-Ω load. The device features programmable gain settings ranging from -1× to -10× via a single resistor, active mute with over 80-dB attenuation, and ±8-kV HBM ESD protection. Key electrical parameters include an SNR greater than 105 dB at -1× gain, noise voltage below 12 μVrms (20 Hz to 20 kHz), and THD+N less than 0.003% at 10-kΩ load.

Audio Amplifiers Feature Summary

• DirectPath architecture generates internal negative rail to enable ground-biased outputs without external DC-blocking capacitors
• Programmable gain selection reduces component count by allowing configuration of 13 distinct gain values using a single resistor
• Integrated active mute control provides pop-free operation with high signal attenuation during power transitions
• Built-in short-circuit and thermal protection safeguards the device under fault conditions

Audio Amplifiers Applications

• PDP and LCD TVs
• DVD Players
• Mini and Micro Combo Systems
• Soundcards

Audio Amplifiers Procurement Notes

Verify that the ordering suffix RGTT corresponds specifically to the 16-pin VQFN package variant as defined in the manufacturer's orderable addendum. Confirm that the specific revision level matches the design requirements, as documentation indicates revisions such as SLOS690C. Ensure compatibility with the intended PCB footprint, noting that this package is footprint-compatible with the TPA6139A2 headphone amplifier.

Audio Amplifiers Selection Notes

Select the DRV612RGTT when board space and cost reduction are critical constraints requiring the removal of bulky output capacitors. This component is suitable for single-supply electronics operating between 3 V and 3.6 V where low noise and high dynamic range are required. Consider the VQFN package for compact designs, ensuring adequate thermal management given the junction-to-ambient resistance characteristics of the small outline package.

Audio Amplifiers Part Context

The DRV612 belongs to Texas Instruments' DirectPath line driver family, designed to simplify audio circuit design by integrating charge pump functionality. It serves as a footprint-compatible alternative to the TPA6139A2 stereo headphone driver, allowing designers to use identical PCB layouts for different audio output configurations. The device addresses common challenges in audio line driving by combining high performance with minimal external component requirements.

Audio Amplifiers Replacement Considerations

The DRV612 is footprint compatible with the TPA6139A2 stereo headphone driver. Designers may substitute one for the other if the PCB layout supports both packages, facilitating flexible board configuration options without redesigning the physical footprint.
